Using Lightroom 4.1 RC2, I selected the first three images in the library grid and did a ccw rotate. Only the first rotated. From this point on, no matter which image or images I selected, rotating those only rotated the first image (it was no longer selected). Even if I rotated an unrelated image in the Develop view, the action was performed on the first image. Changing folders did not help. Quitting and restarting fixed the problem.
